Description

Plastic uptake division board capable of hot riveting

Technical Field

The utility model relates to a battery accessory field, in particular to plastic uptake division board that can rivet hot.

Background

The conventional CCS injection molding isolation plate is easy to have common defects such as material shortage, shrinkage, burrs and mantles, and has space limitation with part assembly, and the occupied volume space in the battery module is also a long-term pain point. The plastic uptake (PC) material has excellent comprehensive performance, excellent electrical insulation, dimensional stability, high strength, heat resistance and cold resistance; it also has the advantages of self-extinguishing, non-toxic, fire-retardant and colourable.

How to effectively solve the disadvantages of the injection-molded separator in the battery module is the subject that the applicant is working on.

SUMMERY OF THE UTILITY MODEL

In order to solve the defects existing in the prior art, the utility model provides a plastic uptake division board that can hot riveting.

In order to realize the purpose, the utility model discloses a technical scheme be: a hot-riveted plastic uptake isolation plate comprises an electric connection plate and an isolation plate; the electric connecting plate is provided with a mounting hole and a sunken electric core area; the isolation plate is made of PC material by plastic suction; the isolating plate is provided with a mounting groove which is matched with the electric connecting plate, and a plastic suction column corresponding to the mounting hole and a through hole for positioning the electric core area are arranged in the mounting groove; the electric connection plate and the isolation plate are connected with each other through the matching of the plastic suction column and the mounting hole; the electric connection plate and the isolation plate are fixedly connected through hot riveting.

After the technical scheme is adopted, the isolation plate is manufactured by carrying out plastic suction molding on the PC material, and the electric connector and the plastic suction column of the plastic suction isolation plate are fixed in a hot riveting mode after clearance assembly. According to the technical scheme, the difficulty of material forming or mold development is greatly reduced compared with injection molding while the volume of the whole CCS is reduced, the mold opening cost of raw materials is low, and the cost is greatly reduced.

The further improvement is that the electric connecting plate is provided with a sinking expansion buffer area in the area close to the electric core; the mounting groove is provided with a buffer groove corresponding to the expansion buffer area. The design of inflation buffer zone is used for the inflation deformation of buffer memory electricity core in welding process, and the dashpot can be used for the fixed buffering zone that spouts a.

In a further improvement, the electric connecting plate is provided with a positioning lug beside the expansion buffer area; the mounting groove is provided with a positioning groove corresponding to the positioning lug. Through the cooperation of location lug and constant head tank, realized the secondary location to the electricity connecting plate and prevented taking place the skew, influence the battery performance.

In a further improvement, at least two cell areas are provided; the expansion buffer region is arranged between two adjacent electric core regions. In order to reduce the production cost, a plurality of cell areas can be arranged on the electric connection board, and a buffer area is arranged between every two adjacent cell areas, so that the deformation caused by expansion can be eliminated to the maximum extent.

In a further improvement, the number of the cell areas is two. The two core regions can improve the efficiency and reduce the volume of the battery. In a further improvement, the positioning lugs are symmetrically arranged on two sides of the expansion buffer area. The positioning lugs are symmetrically arranged on two sides, so that the space is saved while the stability is ensured.

In a further improvement, the positioning lugs are respectively arranged at two ends of the expansion buffer area; the two positioning lugs are respectively arranged on the same side or different sides of the expansion buffer area. The positioning projections are arranged at the two ends, and although the positioning projections are enlarged relative to one side, the positioning projections can achieve greater improvement on the stability of the fixing.
